^Red herrings, no red herrings. I'm not really sure what people expect from this ARG. You'll get a few potatoes on your profile and a few sneak peek images of Portal. Valve is way too cheap to give people actual stuff for solving these silly puzzles.
Note that the games are extended:Toki Tori
bonus Chapter [test] after creating a profile named Potato or #PotatoFoolsDayThe Ball
7 bonus levelsKilling Floor
bonus level (chapter?)The Wonderful End of the World
2 bonus levels (starting Arcadia with pressed U [alternate grayscale version with Shift + I on Word Forge] / P in Sugar Candy)Rush
5 bonus levels after beating a level with removed hints by GlaDOSCogs
bonus levelsBIT.TRIP BEAT
GlaDOS as BossAudiosurf
Portal-modeAmnesia: The Dark Descent
DLC "Justine"AaAaAA! - A Reckless Disregard for Gravity
I don't know what your problem is...I mean we get the games cheaper and with bonus content!
I already backed up my gamecache since these is just temporary.
